Others say that after every mod it can take dozens of changes, dynos, test drives, etc to get a tune right. They mean getting the right combination of HP, torque, throughout the entire usable range, daily driveability, etc.
When I look at their ad, they claim to know Porsches but service a wide mix of cars. Just how knowledgeable are they on a rather unique engine like yours?
You seldom get something for nothing easily and I don't see everyone on the forums leaping on this as opposed to doing other mods which yield very modest gains. Other tuners and mod'ers with considerable experience/resources make no such claims.
